Microinjerto de cabellos y de vellos: sus múltiples indicaciones / Vellus and hair micrografts: Indications

El progreso de los tratamientos actuales, permite proponer una terapéutica médica o quirúrgica adaptada a la importancia de la caída del cabello y de la calvicie para cada paciente. El microinjerto de unidades foliculares y de mini microinjertos es un progreso técnico fundamental. Esta técnica, permite una recuperación capilar definitiva de las calvicies de ciertas regiones pilosas del hombre y de la mujer y aporta de manera simple e indolora, cabellos donde la emergencia por grupos de uno a tres es perfectamente natural. La diferencia entre los receptores androgénicos de las regiones occipitales y de las otras regiones, explica el carácter definitivo del crecimiento de los cabellos reimplantados. El grado de calvicie de una alopecia androgenética masculina o femenina puede ser evaluado de acuerdo a una clasificación estática (Hamilton, Ludwig) o ser medido y seguido con más precisión, con una clasificación dinámica plurifactorial (Bouhanna). Todas ías indicaciones actuales de microinjertos son: - Las alopecias androgenéticas masculinas de los estadios III a VII - Las alopecias androgenéticas femeninas de los estadios I a III - El llenado de las entradas en los transexuales - Las alopecias cicatriciales - Las alopecias de las cejas - Las cicatrices de la barba y del bigote - La alopecia del pubis

Advances in treatments of androgenetic alopecia have led to the development of novel medical or surgical therapies adapted to the severity of hair loss and balding. Follicular units or tiny micrograft hair transplants are a fundamental technical progress. This technique leads to the simple and painless permanent restoration of hair in male and female baldness It provides the patient with a group of 1 to 3 hairs, emerging from a single orifice. The difference between androgenetic receptors of occipital areas and those of other areas explains the permanent nature of the implanted hairs growth. The degree of male or female androgenetic alopecia can be determined according to Hamilton's static classification or Ludwig's Classification, or it can be measured and monitored more accurately with Bouhanna's Dynamic Multifactorial Classification. The current indications of micrograft transplantation are: - Male androgenetic alopecia (Hamilton 111 to VII) - Female androgenetic alopecia (Ludwig 1 to 111) - Frontal recession hair transplantation in transsexuals - Cicatricial alopecia - Alopecia of the eyebrows - Bald spots of the beard and moustache - Alopecia of the pubis

Androgenetic alopecia: combining medical and surgical treatments.

BACKGROUND: Medical treatment or surgical reconstruction is used separately to treat androgenetic alopecia. Two drug molecules (5% minoxidil solution and oral finasteride 1 mg) have proven efficacy to stabilize hair loss and promote hair regrowth. Microtransplant of one to three hair follicular unit grafts can provide a definitive hair restoration with a natural appearance. OBJECTIVES: Aesthetic results can be optimized with a combination of drugs and transplantation of follicular unit grafts. The Dynamic Multifactorial Classification is used to select suitable candidates for this combined approach and also to assess follow-up results. RESULTS: Dynamic Multifactorial Classification assists the evaluation of the natural history of androgenetic alopecia evolution and also the effects of treatment. Regression of male androgenetic alopecia from Hamilton type V to type III can be achieved by combining drugs with hair grafts. CONCLUSION: Improvement of investigative methods and especially the Dynamic Multifactorial Classification makes it easier for a patient to follow the results of treatment adapted to their case.
